在vb.net同样可以将报表导出到excel和word进行输出，制作出专业水平的报表。具体操作如下：(注：首先需添加引用，选择com-->选择microsoft word object library和microsoft excel object library组件)
private function creatable() as datatable dim dt as new datatable() dt.columns.add("列1", gettype(string)) dt.columns.add("列2", gettype(integer)) dt.columns.add("列3", gettype(string)) dt.columns.add("列4", gettype(string)) dim row, row1 as datarow row = dt.newrow() row!列1 = "行1" row!列2 = 1 row!列3 = "d" row!列4 = "a" dt.rows.add(row) row1 = dt.newrow() row1!列1 = "行2" row1!列2 = 12 row1!列3 = "b" row1!列4 = "c" dt.rows.add(row1) return dt end function
